BALL BEAR-Ina.

Application filed December c, 1928. Serial no. 152,741.

My invention relates to improvements in ball bearings and has for one object to provide a new and improved type of ball bearing wherein the ball spacing elements may be easily and conveniently assembled with the balls and wherein the creeping or traveling of the balls with respect to each other is not able to exert any lateral disrupting effect on the retainer rings and wherein anti-friction means are interposed between adjacent balls to prevent binding and clamping of the balls in their traveling action. Other objects will appear from time to time throughout the specification and claims.

My invention is illustrated more or less diagrammatically in the accompanying drawings, wherein- Figure 1 is a side elevation in part section;

Figure 2 is a section along the line 22 of Figure l;

Figure 3 is a section along the line 33 oi Figure l; i I

Figure 4 is a section along the line 4-4: ot Figure 1;

Figure 5 is a side elevation of the ball cage;

Figure 6 is an edge elevation of the ball cage;

Figure 7 is a plan view of the removable cage ring.

Like parts are indicated by like characters throughout the specification and drawings.

A is the inner race, A the outer race. These races are channelled as at A in the usual manner. A A are a series of balls adapted for travel between the two races.

The ball cage shown in general in Figures 5 and 6 comprise the fixed ring 13, a plurality of filler blocks B projecting laterally there: from, there being s ace between each pair 0t filler blocks for a l all and a cover ring B adapted to close such space in opposition to the fixed ring B. Rivets B pass through the filler blocks B and the cover ring 13 to hold them together when the apparatus is assembled. It will be noted that the filler blocks each having a reinforced belt 13* project outwardly from the periphery thereof.

Each of the filler blocks B is socketed and in each socket is an anti-friction roller C. The socket terminates in a conical end 0 in the ring B adapted to be engaged by the comcal end of the roller C. The cover ring B has a series of bosses C thereon which bosses are socketed like the sockets in the fixed ring B to engage the opposed end of the rollers. The

rivets B pass through the hollow interior of these rollers and are out of contact therewith so that the only bearing between the rollers and cage or ring is at the opposed ends of the roller in the conical sockets. These rollers are spaced between the balls and project beyond the filler blocks so that each ballis in engagement with the rollers and not in engagement with the fixed filler block thereby permitting rotary movement of the rollers in enga ement with the balls and furnishing an anti riction hearing or contact for the balls.

I claim:

l. A spacing cage for anti-friction bearof members and anti-friction spacing members carried by the spacer blocks out of contact with the race and inengagement with the load carrying members, the anti-fricmounted rollers.

3. In a ball bearing, inner and outer races, balls free to travel therebetween, spacer blocks interposed between adjacent balls, rings on each side of the group of blocks and balls adapted to hold the blocks in place between the balls, roller hearings in each block.

interposed between and adapted to be engaged by the balls.

4. In a ball bearing, inner and outer races, balls free to travel therebetween, spacer blocks interposed between adjacent balls, rings on each side of the group of balls and blocks adapted to hold the blocks in place between the balls, roller bearings in each block interposed between and adaptedto be 'tion spacing members comprising rotatably engaged by the balls, said roller bearings comprising cylinders tapered at their ends, there being sockets in the opposed rings to engage said tapered cylinder ends.

5. In a ball bearing, inner and outer races, balls free to travel therebetween, s acer blocks interposed between adjacent a lls,

rings on each side of the group of balls and ing hollow tie-rods extending through but blocks adapted to hold the blocks in place be out of contact with the cylinders and adapted 10 tween the balls, roller hearings in each block to hold the rings together.

interposed between and adapted to be en- Signed at Chicago, county of Cook and gaged by the balls, said roller bearings com- State of Illinois, this 3rd day of December prising cylinders tapered at their ends, there 1926.
